High Efficiency Grinding Vertical Roller Mill HVM1700 for Calcite & Calcium Carbonate Grinding
High Efficiency Grinding Vertical Roller Mill HVM1100 for Calcite & Calcium Carbonate Grinding
Description
The calcite vertical mill is an advanced industrial grinding equipment specially designed for grinding calcite (calcium carbonate) to various fineness levels. It adopts a mature vertical structure design and an efficient material bed grinding principle, which can process massive calcite into various products ranging from coarse powder (80 meshes) to ultra-fine powder (up to more than 2500 meshes). It is an efficient and energy-saving alternative to traditional Raymond mills and ball mills.
Core Working Principle
1. The core working principle of the calcite vertical mill lies in the perfect combination of "material bed grinding" and "high-efficiency classification". The process is as follows:
2. Feeding: Raw calcite is fed into the mill through an air-locked feeder and falls onto the center of the rotating grinding disc.
3. Rolling & Crushing: The centrifugal force generated by the rotation of the grinding disc brings the material between the grinding rollers and the grinding disc. The grinding rollers, pressed by the hydraulic system, roll and crush the material.
4. Drying & Conveying: The crushed powdery material is blown up by the hot air flow (optional, for drying purposes) entering from the bottom and conveyed to the dynamic classifier at the top.
5. Classification: The high-speed rotating classification impeller separates the powder that meets the fineness requirement, which then enters the collection system along with the air flow; the unqualified coarse powder is thrown back to the grinding disc for re-grinding.
6. Collection: The qualified finished powder enters the high-efficiency pulse bag filter along with the air flow, is collected, and becomes the final product.
This closed-loop system ensures extremely high grinding efficiency, low energy consumption, and precise fineness control.

Advantages of calcite vertical mill:
Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption, compared to ball mills, the energy consumption is 40% -50% lower;
(2) Large single machine production capacity, capable of utilizing low valley electricity;
(3) Vertical grinding technology and equipment are vigorously advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitive strength of enterprises in the powder industry in this region and even across the country;
Easy maintenance and low operating costs:
(1) The grinding roller can be turned out of the machine using a hydraulic device, and the replacement of the roller sleeve lining plate and the maintenance space of the mill are large, making the maintenance operation very convenient;
(2) The grinding roller sleeve can be used upside down, extending the service life of wear-resistant materials;
(3) Before starting the machine, there is no need to apply fabric to the grinding disc, and the mill can be started without load, eliminating the difficulty of starting the machine;
(4) Low wear, special materials are used for the grinding roller and disc lining plate, resulting in a long service life;
(5) High degree of automation: The automatic control technology adopts the Siemens series PLC from Germany, equipped with an automatic control system, which can achieve remote control and easy operation. The workshop can basically achieve unmanned operation, saving operating costs;
Low comprehensive investment cost:
Integrating crushing, drying, grinding, and conveying, the process flow is simple, the system equipment is few, the structural layout is compact, and the floor area is only 50% of that of the ball mill. It can be arranged outdoors, with low construction costs, directly reducing the investment cost of the enterprise.
Stable product quality:
(1) The material stays in the grinder for a short time, making it easy to detect the particle size distribution and composition of the product, and ensuring stable product quality;
(2) The product has uniform particle morphology, narrow particle size distribution, good flowability, and strong product adaptability.
High reliability
(1) Adopting a grinding roller limit device to avoid severe vibration caused by material breakage during the working time of the mill;
(2) Adopting a new type of roller sealing device, the sealing is more reliable, and there is no need for a sealing fan, further reducing the oxygen content in the mill and achieving better explosion suppression performance.
Environmental protection:
(1) The entire system of HVM vertical grinding machine has low vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and there is no dust leakage, basically achieving a dust-free workshop.
